DS2155

T1/E1/J1 Single-Chip Transceiver

www.maxim-ic.com

GENERAL DESCRIPTION

FEATURES

The DS2155 is a software-selectable T1, E1, or J1

single-chip transceiver (SCT) for short-haul and

long-haul applications. The DS2155 is composed of a

line interface unit (LIU), framer, HDLC controllers,

and a TDM backplane interface, and is controlled by

an 8-bit parallel port configured for Intel or Motorola

bus operations. The DS2155 is pin and software

compatible with the DS2156.

Complete T1/DS1/ISDN-PRI/J1 Transceiver

Functionality

Complete E1 (CEPT) PCM-30/ISDN-PRI

Transceiver Functionality

Long-Haul and Short-Haul Line Interface for

Clock/Data Recovery and Waveshaping

CMI Coder/Decoder for Optical I/F

Crystal-Less Jitter Attenuator

ꢀ

Fully Independent Transmit and Receive

Functionality

The LIU is composed of transmit and receive

interfaces and a jitter attenuator. The transmit

interface is responsible for generating the necessary

waveshapes for driving the network and providing

the correct source impedance depending on the type

of media used. T1 waveform generation includes

DSX-1 line buildouts as well as CSU line buildouts

of -7.5dB, -15dB, and -22.5dB. E1 waveform

generation includes G.703 waveshapes for both 75Ω

coax and 120Ω twisted cables. The receive interface

provides network termination and recovers clock and

data from the network.
